NOTE: in botany ‘effusus,-a,-um (part.A)’ appears to be a synonym: effuse, spread out flat, without definite form, as in lichens (WIII); diffusus seems to be more used for shrubs: (of branches) spreading widely or loosely, spreading in all directions, straggling. Effusus seems more used for branching organs, such as umbels, panicles, etc.; see effusus,-a,-um (part.A). Effusus is used by Nylander in lichens more than diffusus;
